The place that much needs heat at the petroleum recovering multi-purpose station in addition.Such as, in order to improve crude oil temperature, reduce viscosity of crude, improve the flowability of crude oil, adopting companion's hot mode is heating crude oil in the conveyance conduit, improves the oil temperature.Especially at the crude oil exporting of north of china in winter or heavy oil block, heating crude oil to 50 ℃-75 ℃ could must be guaranteed the Crude Oil Transportation process safe.Oil pipe companion hot mode is to utilize oven that water temperature is brought up to 60-70 ℃, and hot water piping and original pipeline are adjacent to side by side and install, the heat transferred crude oil pipeline of hot water piping, heating in crude oil.For another example, also need use a large amount of heat energy in individual well thermal cycle and the life.At the petroleum recovering multi-purpose station, the natural gas engine group has a large amount of heat energy dissipations every day; On the other hand, the substantial oil that needs again to burn obtains that heat is used for producing and life.The fine recycling of failing of the waste heat of natural gas engine group had both increased energy consumption, improved the oil recovery cost of production, again environment was polluted.
Summary of the invention
The purpose of this utility model is: a kind of oil recovery multi-purpose station natural gas engine waste heat recovering device is provided, natural gas engine group cylinder body waste heat and flue residue heat are reclaimed, use in production and the life; reduce discharges heat; reduce energy consumption, reduce production costs, the protection environment.
The utility model is that the technological scheme that its technical problem of solution is taked is: in the natural gas engine cylinder body hydrologic cycle cooling system pipeline plate type heat exchanger is installed, be that the engine cycles water out connects the plate type heat exchanger water inlet, the plate type heat exchanger water out connects water pump, and water pump connects the engine cycles water inlet.Form an engine cooling water circulation system.The hot water that engine cylinder-body is discharged is behind plate type heat exchanger, and temperature reduces, with heat transferred heat recovery water circulation system.The heat recovery water circulation system adopts water pump to connect the plate type heat exchanger cold water inlet, and the plate type heat exchanger water outlet connects the water intake of device for recovering residual heat of flue.Device for recovering residual heat of flue is installed in the middle of engine stack.Device for recovering residual heat of flue water outlet, connection need provide TRACER, individual well Circulation pipe or the heating for residential area etc. of thermal source.Through behind TRACER, individual well Circulation pipe or the heating for residential area, the heat recovery coolant-temperature gage reduces.Water pump is sent heat recovery water into the plate type heat exchanger cold water inlet.Heat recovery water forms circulation like this, and engine cylinder-body waste heat and engine stack waste heat are passed to production, life usefulness, and engine exhaust heat is fully used.
The beneficial effects of the utility model are: adopt plate type heat exchanger and device for recovering residual heat of flue serial fashion; reclaim natural gas engine cylinder body waste heat and natural gas engine flue residue heat; waste heat is fully reclaimed; recovery waste heat is used for producing and life; minimizing is discharges heat in air; improved the thermal efficiency, energy saving, protection environment.
